Globalization, first-foods systems transformations and corporate power: a synthesis of literature and data on the market and political practices of the transnational baby food industry
Publisher: Springer Science and Business Media LLC
Date: 21-05-2021
DOI: 10.1186/S12992-021-00708-1
Abstract: The global milk formula market has ‘boomed’ in recent decades, raising serious concerns for breastfeeding, and child and maternal health. Despite these developments, few studies have investigated the global expansion of the baby food industry, nor the market and political practices corporations have used to grow and sustain their markets. In this paper, our aim is to understand the strategies used by the baby food industry to shape ‘first-foods systems’ across its erse markets, and in doing so, drive milk formula consumption on a global scale. We used a theoretically guided synthesis review method, which integrated erse qualitative and quantitative data sources. Global milk formula sales grew from ~US$1.5 billion in 1978 to US$55.6 billion in 2019. This remarkable expansion has occurred along two main historical axes. First, the widening geographical reach of the baby food industry and its marketing practices, both globally and within countries, as corporations have pursued new growth opportunities, especially in the Global South. Second, the broadening of product ranges beyond infant formula, to include an array of follow-up, toddler and specialized formulas for a wider range of age groups and conditions, thereby widening the scope of mother-child populations subject to commodification. Sophisticated marketing techniques have been used to grow and sustain milk formula consumption, including marketing through health systems, mass-media and digital advertising, and novel product innovations backed by corporate science. To enable and sustain this marketing, the industry has engaged in erse political practices to foster favourable policy, regulatory and knowledge environments. This has included lobbying international and national policy-makers, generating and deploying favourable science, leveraging global trade rules and adopting corporate policies to counter regulatory action by governments. The baby food industry uses integrated market and political strategies to shape first-foods systems in ways that drive and sustain milk formula market expansion, on a global scale. Such practices are a major impediment to global implementation of the International Code of Marketing of Breastmilk Substitutes, and other policy actions to protect, promote and support breastfeeding. New modalities of public health action are needed to negate the political practices of the industry in particular, and ultimately to constrain corporate power over the mother-child breastfeeding dyad.

Critical Velocity and Backlayering Conditions in Rail Tunnel Fires: State-of-the-Art Review
Publisher: Hindawi Limited
Date: 28-05-2019
DOI: 10.1155/2019/3510245
Abstract: The use of interurban and urban trains has become the preferred choice for millions of daily commuters around the world. Despite the huge public investment for train technology and mayor rail infrastructure (e.g., tunnels), train safety is still a subject of concern. The work described herein reviews the state of the art on research related to critical velocity and backlayering conditions in tunnel fires. The review on backlayering conditions includes the effect of blockages, inclination, and the location of the fire source. The review herein focuses on experimental and theoretical research, although it excludes research studies using numerical modeling. Many studies have used scaled tunnel structures for experimental testing nevertheless, there are various scaling challenges associated with these studies. For ex le, very little work has been done on flame length, fire source location, and the effect of more than one blockage, and how results on scaled experiments represent the behaviour at real-scale. The review sheds light on the current hazards associated with fires in rail tunnels.

Predictive testing for heat-induced spalling of concrete
Publisher: International Association for Bridge and Structural Engineering (IABSE)

DOI: 10.2749/222137815818358123
Abstract: This paper describes a project which sets out to define a practical predictive test method for heat- induced explosive spalling of concrete. The method is based on a novel testing apparatus known as the Heat-Transfer Rate Inducing System (H-TRIS), previously developed at The University of Edinburgh. A series of 75 s les were tested using a large-scale standard fire testing furnace at CERIB (France) and using H-TRIS in Edinburgh. Within the scope of this project, a thorough examination of the thermal exposure was carried out in order to ensure repeatability of the thermal exposure imposed during testing. The H-TRIS method and apparatus was successful in accurately replicating the thermal exposures experienced by s les in the fire testing furnace when testing to both the ISO 834 and modified hydrocarbon (HCM) standard fire curves. The testing has also provided insights into the influence of s le size, polypropylene fibre content, and moisture content on the propensity for heat-induced concrete spalling.
Concrete Fire Testing - A Review of the Thermal Boundary Conditions
Publisher: Trans Tech Publications, Ltd.
Date: 09-2016
DOI: 10.4028/WWW.SCIENTIFIC.NET/KEM.711.496
Abstract: Experimental studies of concrete in fire or at elevated temperature have traditionally given relatively little scientific attention to quantifying the severity, and to some extent reproducibility, of the thermal boundary conditions imposed on specimens during testing. This paper examines the heat transfer fundamentals of fire testing when controlling the time-history of temperature inside a furnace (or oven), versus controlling the time-history of incident radiant heat flux at a specimen’s exposed surface. The thermal boundary conditions of a concrete specimen during fire testing are fundamentally based on conservation of energy, and thus typically formulated in terms of heat fluxes. While from the standpoint of concrete fire behaviour the aim is typically only to gauge the distribution of temperatures inside concrete this is rarely explicitly acknowledged or quantified during concrete fire testing. This shows that continued unexamined use of varied heating techniques presents a serious threat to harmonization of the thermal boundary conditions imposed during concrete testing. The current work proposes adopting test control by in-depth temperature distributions or net heat fluxes for a rigorous comparison of the thermal boundary conditions imposed on test specimens when using different heating techniques.

Bioinspired, Highly Adhesive, Nanostructured Polymeric Coatings for Superhydrophobic Fire-Extinguishing Thermal Insulation Foam
Publisher: American Chemical Society (ACS)
Date: 25-06-2021
Abstract: Lightweight polymeric foam is highly attractive as thermal insulation materials for energy-saving buildings but is plagued by its inherent flammability. Fire-retardant coatings are suggested as an effective means to solve this problem. However, most of the existing fire-retardant coatings suffer from poor interfacial adhesion to polymeric foam during use. In nature, snails and tree frogs exhibit strong adhesion to a variety of surfaces by interfacial hydrogen-bonding and mechanical interlocking, respectively. Inspired by their adhesion mechanisms, we herein rationally design fire-retardant polymeric coatings with phase-separated micro/nanostructures via a facile radical copolymerization of hydroxyethyl acrylate (HEA) and sodium vinylsulfonate (VS). The resultant waterborne poly(VS- co -HEA) copolymers exhibit strong interfacial adhesion to rigid polyurethane (PU) foam and other substrates, better than most of the current adhesives because of the combination of interfacial hydrogen-bonding and mechanical interlocking. Besides a superhydrophobic feature, the poly(VS- co -HEA)-coated PU foam can self-extinguish a flame, exhibiting a desired V-0 rating during vertical burning and low heat and smoke release due to its high charring capability, which is superior to its previous counterparts. Moreover, the foam thermal insulation is well-preserved and agrees well with theoretical calculations. This work offers a facile biomimetic strategy for creating advanced adhesive fire-retardant polymeric coatings for many flammable substrates.

Breastfeeding, first-food systems and corporate power: a case study on the market and political practices of the transnational baby food industry and public health resistance in the Philippines
Publisher: Springer Science and Business Media LLC
Date: 26-10-2021
DOI: 10.1186/S12992-021-00774-5
Abstract: The aggressive marketing of breastmilk substitutes (BMS) reduces breastfeeding, and harms child and maternal health globally. Yet forty years after the World Health Assembly adopted the International Code of Marketing of Breast-milk Substitutes (The Code), many countries are still to fully implement its provisions into national law. Furthermore, despite The Code, commercial milk formula (CMF) markets have markedly expanded. In this paper, we adopt the Philippines as a case study to understand the battle for national Code implementation. In particular, we investigate the market and political strategies used by the baby food industry to shape the country’s ‘first-food system’, and in doing so, promote and sustain CMF consumption. We further investigate how breastfeeding coalitions and advocates have resisted these strategies, and generated political commitment for a world-leading breastfeeding policy framework and protection law (the ‘Milk Code’). We used a case study design and process tracing method, drawing from documentary and interview data. The decline in breastfeeding in the Philippines in the mid-twentieth Century associated with intensive BMS marketing via health systems and consumer advertising. As regulations tightened, the industry more aggressively promoted CMFs for older infants and young children, thereby ‘marketing around’ the Milk Code. It established front groups to implement political strategies intended to weaken the country’s breastfeeding policy framework while also fostering a favourable image. This included lobbying government officials and international organizations, emphasising its economic importance and threats to foreign investment and trade, direct litigation against the government, messaging that framed marketing in terms of women’s choice and empowerment, and forging partnerships. A resurgence in breastfeeding from the mid-1980s onwards reflected strengthening political commitment for a national breastfeeding policy framework and Milk Code, resulting in-turn, from collective actions by breastfeeding coalitions, advocates and mothers. The Philippines illustrates the continuing battle for worldwide Code implementation, and in particular, how the baby food industry uses and adapts its market and political practices to promote and sustain CMF markets. Our results demonstrate that this industry’s political practices require much greater scrutiny. Furthermore, that mobilizing breastfeeding coalitions, advocacy groups and mothers is crucial to continually strengthen and protect national breastfeeding policy frameworks and Code implementation.

Effects of temperature and temperature gradient on concrete performance at elevated temperatures
Publisher: SAGE Publications
Date: 08-12-2017
Abstract: To assure adequate fire performance of concrete structures, appropriate knowledge of and models for performance of concrete at elevated temperatures are crucial yet currently lacking, prompting further research. This article first highlights the limitations of inconsistent thermal boundary conditions in conventional fire testing and of using constitutive models developed based on empirical data obtained through testing concrete under minimised temperature gradients in modelling of concrete structures with significant temperature gradients. On that basis, this article outlines key features of a new test setup using radiant panels to ensure well-defined and reproducible thermal and mechanical loadings on concrete specimens. The good repeatability, consistency and uniformity of the thermal boundary conditions are demonstrated using measurements of heat flux and in-depth temperature of test specimens. The initial collected data appear to indicate that the compressive strength and failure mode of test specimens are influenced by both temperature and temperature gradient. More research is thus required to further quantify such effect and also to effectively account for it in rational performance-based fire design and analysis of concrete structures. The new test setup reported in this article, which enables reliable thermal/mechanical loadings and deformation capturing of concrete surface at elevated temperatures using digital image correlation, would be highly beneficial for such further research.
Integrative and comparative genomic analyses identify clinically relevant pulmonary carcinoid groups and unveil the supra-carcinoids
Publisher: Springer Science and Business Media LLC

DOI: 10.1038/S41467-019-11276-9
Abstract: The worldwide incidence of pulmonary carcinoids is increasing, but little is known about their molecular characteristics. Through machine learning and multi-omics factor analysis, we compare and contrast the genomic profiles of 116 pulmonary carcinoids (including 35 atypical), 75 large-cell neuroendocrine carcinomas (LCNEC), and 66 small-cell lung cancers. Here we report that the integrative analyses on 257 lung neuroendocrine neoplasms stratify atypical carcinoids into two prognostic groups with a 10-year overall survival of 88% and 27%, respectively. We identify therapeutically relevant molecular groups of pulmonary carcinoids, suggesting DLL3 and the immune system as candidate therapeutic targets we confirm the value of OTP expression levels for the prognosis and diagnosis of these diseases, and we unveil the group of supra-carcinoids. This group comprises s les with carcinoid-like morphology yet the molecular and clinical features of the deadly LCNEC, further supporting the previously proposed molecular link between the low- and high-grade lung neuroendocrine neoplasms.

Effects of substrate thermal conditions on the swelling of thin intumescent coatings

Date: 21-04-2020
DOI: 10.1002/FAM.2840
Abstract: The experimental study presented herein investigates the influence of the substrate thermal conditions on the behaviour of thin intumescent coatings. Steel plates coated with a commercially available solvent‐based thin intumescent coating were exposed to a constant incident radiant heat flux of 50 kW/m 2 in accordance with the heat‐transfer rate inducing system (H‐TRIS) test method. The influence of different substrate thermal conditions was investigated using s le holders capable of controlling the thermal boundary conditions at the unexposed surface of tested steel plates and comparing them to coated timber s les. Experimental results evidence that the substrate thermal conditions govern the swelling of intumescent coatings, thus their effectiveness in protecting load‐bearing structural elements. The substrate temperature controls the swelling of intumescent coatings because it defines the temperature experienced by the reacting virgin coating located close to the coating‐substrate interface. The physical and thermal properties of the substrate control the capacity of the system to concentrate/dissipate heat in proximity of the coating‐substrate interface. In this way, the substrate thermal conditions govern the temperature evolution of the reacting intumescent coating, consequently the swelling process. Accordingly, high swelling rates were recorded for highly insulating conditions (timber substrate), while low swelling rates for poorly insulating conditions (water‐cooled heat sink).

Fire performance of metal-free timber connections
Publisher: Thomas Telford Ltd.
Date: 08-2015
Abstract: The fire performance of heavy timber frame structures is often limited by the poor fire performance of its connections. Conventional timber connections, dowelled or toothed plate connections typically use steel as a connector material. In a fire, the steel parts rapidly conduct heat into the timber, leading to reduced fire performance. Replacing metallic connectors with alternative non-metallic, low thermal conductivity connector materials can, therefore, lead to improved connection performance in fire. This paper presents an experimental study into the fire performance of metal-free timber connections comprising a hot-pressed plywood flitch plate and glass-fibre-reinforced polymer dowels. The thermal behaviour of the connections at elevated temperatures is studied using a standard cone calorimeter apparatus and a novel heat transfer rate inducing system. The latter is a fire testing system developed at the University of Edinburgh. The mechanical behaviour of the connection during severe heating was also studied using an environmental chamber at temperatures up to 610°C. The results demonstrate that heat transfer in the non-metallic connections is governed by the thermal properties of the timber, resulting in significant enhancements in connection fire performance.
